Kelly E. Fast (b. 1968) is a program scientist for the MAVEN spacecraft at NASA. She has measured planetary atmospheric compositions and winds, most notably the ozone abundance on Mars, using the HIPWAC instrument at the NASA Infrared Telescope Facility. She is a gifted singer, as featured in "Hotel Mauna Kea".
